It is not his job to "warn" him by threat on a podcast. That is just idiocy, and gave them an opening to create a "victim" narrative and get public opinion on their side. If he would not act like a Gangster that is giving them an "Offer youse can't refuse" we'd all be better off. Why is this difficult for you?
Carr's job, warn them, yes. Carr's job does not include doing it through incredibly childish and improper podcast threats creating the narrative for the leftists to use to get him a path back to TV.
